1) You can now delete members right from your site. If you are logged in as the site owner, there is a new “delete member” link on your members’ profiles. You don’t have to be in the sitebuilder anymore to perform this action.

2) When a member is deleted, they can no longer rejoin the site immediately. Instead, they will sit as a “pending member” until you approve them. This is part of the member banning option that a lot of you have been asking for.
